Calvin Klein Underwear is some of the best-fitting underwear out there and their T-shirts are no different. They fit spectacularly and are our go-to t-shirt here at GQ. As much as the brand's ad campaigns are edgy and progressive, they do iconic American basics uncompromisingly well. These t-shirts have a precisely cut sleeve that fits around the arm perfectly and ribbing at the neck that's just the right width. It's a chance to own a little bit of that James Dean mystique and mojo for not a lot of money.
